Classification and application fields of Rocker Switches


The Rocker Switch is a common type of electronic switch. It connects or disconnects the circuit by pressing one end of the switch. The operation is simple and the feel is clear. It is widely used in household appliances, industrial equipment, automotive electronics and other fields.
The following are the common classifications and characteristics of switches for different ship types:
1. Classified by the number of poles.
Single Pole Single Knife (SPST)
The simplest boat-shaped switch has only one contact and its function is "on/off".
Example: Light switches, power switches for small household appliances.
Single-pole double-pole (SPDT)
One input contact and two output contacts can switch between two circuit states.
Example: Control the forward and reverse rotation of the motor.
Bipolar Double-knife (DPDT)
Two sets of independent contacts can control two circuits simultaneously.
Devices that require synchronous switching of complex circuits.
2. Classification by function
Normally open type (NO)
By default, it is disconnected. Press it to reconnect the circuit.
Normally closed type (NC)
By default, it is connected. Press it to disconnect the circuit.
Self-reset switch
It is connected when pressed and automatically resets when released (such as the opening and closing of a car window).
3. Classified by installation method
Panel-mounted type
It is directly fixed on the equipment panel and fixed by nuts or clips.
It is applicable to industrial control consoles, audio equipment, etc.
Guide rail installation type
It is installed on electrical rails and is commonly found in industrial power distribution systems.
4. Classified by protection level
Standard type (IP20)
It has no waterproof or dustproof design and is suitable for dry environments.
Waterproof and dustproof type (IP65/IP67)
Sealed design, resistant to splashing water or brief immersion.
Outdoor equipment, car engine compartment switches.
5. Classified by size and appearance
Standard type
Common sizes such as 15×21mm and 20×30mm are suitable for general scenarios.
Mini type
Miniaturized design (such as 10×15mm), for compact Spaces.
Color/Custom type
Multiple colors or customized logos
The Rocker Switch mainly serves functions such as circuit on-off control, status switching and safety protection. The following are its main application fields and specific functions:
1.Household appliances
Application equipment: rice cooker, microwave oven, electric fan, air purifier, coffee machine, etc.
Function:
Power control: The power on/off of the equipment is achieved through a single-pole single-pole (SPST) switch.
Function switching: Such as adjusting the speed of an electric fan (switching between high and low speeds through SPDT or combination switches).
Safety protection: The boat-shaped switch with a fuse can prevent the circuit from being damaged due to overload.
2. Industrial equipment
Application equipment: machine tools, PLC control cabinets, distribution boxes, conveyor belts, etc.
Function:
Motor control: The forward and reverse rotation or start and stop of the motor are controlled by a bipolar double-pole (DPDT) switch.
Emergency power-off: A red self-resetting boat-shaped switch is used for emergency stop of equipment.
Waterproof and dustproof: Switches with an IP67 protection rating are used in damp or dusty environments (such as food processing equipment).
3. Automotive electronics
Application equipment: car audio system, window lift, seat heating, lighting system, etc.
Function:
Window control: A short press of the reset switch triggers the window to rise and fall (releasing it stops immediately).
Power management: Normally open switches control the power supply of on-board devices (such as dash cams).
4. Medical equipment
Application equipment: ventilators, monitors, electric hospital beds, etc.
Function:
Safety isolation: The bipolar switch completely cuts off the power supply of high-risk equipment (such as surgical instruments).
Anti-accidental touch: The boat-shaped switch with a protective cover prevents accidental operation.
Easy to clean: The waterproof and sealed design supports wiping with disinfectant.
5. Smart Home and Internet of Things
Application equipment: smart sockets, smart lamps, security systems, etc.
Function:
Manual override: When an intelligent device malfunctions, it forces the control circuit through a physical switch.
Status indication: The switch with LED light shows the networking or power supply status of the device.
6. Consumer electronic products
Application devices: game controllers, audio equipment, electronic toys, etc.
Function:
User interaction: The mini boat-shaped switch is used for mode switching (such as silent/game mode).
